| Abstract: | Based on the test results of bond-glide constitutive relation between soil and structure interface,combining with physical simulation results,the dynamic variation laws of internal force and displacement of the light weight steel portal frame construction with 24m span under the elongation,compression,decline,positive curvature and negative curvature deformation of surface are calculated by numerical simulation method using the structural finite element analysis software-ANSYS.The applicable effects and mechanisms of different measures of reinforcement and protection are studied.Which provides design reference and engineering parameters for the light weight steel portal frame constructions to be used in surface deformation areas. |
